Win% represents the percent games played that were won.
Games Won + ( Games Tied × 0.5 ) ) ÷ Games Played = Win%
( 5 + ( 0 × 0.5 ) ) ÷ 10 = 50.0%
SOS1 represents the average of opponents' Win% for each game.
AVERAGE(
100.0%
57.1%
53.8%

SOS2 represents the average of opponents' SOS1.
AVERAGE(

0.538
0.296

RPI represents the Ratings Percentage Index
( 40% × Win% ) + ( 40% × SOS1 ) + ( 20% × SOS2 ) = RPI
( 40% × 0.500 ) + ( 40% × 0.606 + ( 20% × 0.418 ) = 0.440
( 0.200 ) + ( 0.242 ) + ( 0.084 ) = 0.440
